Have you ever tried using the terminal exclusively for your day-to-day usage for any amount of time?

I live about 90% in various terminal windows.

I'm multi-machine and play in my homelab stuff a lot, so I sit in mosh/tmux/vim all day long. This has been my usual experience for a long long time. My experimentation tends to be on the GUI side of things, trying out this "vs code" thing everyone is talking about...

but I'll still never live without a GUI, browsing sucks so hard in a terminal now. It's basically unworkable.

No because why would I? Various things, like browsing the web as you mentioned, aren't made for the terminal. I see literally no point in trying to use the terminal for everything, I already have enough use-cases for it.

I3wm here. I haven't used a real linux DE since I ran Unity on my netbook. I use terminal apps for almost everything except web browsing and krita

Around 10 years ago after the radeon xorg driver broke for the nth time on my arch install, I decided to just ditch Xorg altogether. I used screen for multiplexing, mutt for mail, irssi and some other messanger and w3m with (framebuffer support for images) for browsing the interwebs. I also had a videoplayer. I think it was mplayer. I rocked that setup for almost a year during college. Fun times.

I don't think I could ever give up GUI completely. I would not be able to work without GUI tools for coding, making presentations, editing documents, etc. I don't want to memorize terminal commands for things that are easier / quicker to get done with a GUI. Also, what about gaming?

I try to make a habit of using the terminal for as much as I can, which honestly is a lot. I've even found a way to use it at work.

One day, I plan to run Linux without a window manager, maybe even without xorg entirely, using the tty's exclusively.
